fix(antigravity): humanize raw model id labels and add localization fallback

CHANGELOG.md

@@ -20,6 +20,7 @@
 - Codex pace: extrapolate historically exhausted weeks for run-out forecasts and avoid contradictory reset headlines. Thanks @Yuxin-Qiao!
 - Settings: switch tabs immediately before animated window resizing and reduce Providers sidebar work. Thanks @elijahfriedman!
 - Windsurf: import complete Devin sessions from the current app origin before legacy browser storage. Thanks @kiranmagic7!
+- Antigravity: humanize raw model identifiers while preserving server-provided quota labels. Thanks @bcharleson!
 - Menu bar: show provider status markers only for the provider rendered in each icon. Thanks @Zihao-Qi!
 - Codex CLI: make automatic usage reads prefer OAuth and CLI sources instead of blocking on the optional web dashboard.
 - Codex web: apply `--web-timeout` to the full cookie import, account verification, retry, and dashboard fetch path.
